'Sure' in the Bible

Beware of being negligent in carrying out this matter. Why should damage increase to the detriment of the kings?”

And be sure that you don't fail to provide their daily needs including young bulls, rams, and lambs for the burnt offerings of the God of Heaven, along with wheat, salt, wine, and oil, as the priests in Jerusalem tell you

With this money you should be sure to purchase bulls, rams, and lambs, along with the appropriate meal offerings and libations. You should bring them to the altar of the temple of your God which is in Jerusalem.
